L. MANN ET AL. PACKING UNIT FOR AND METHOD OF PACKING FRAGILE ARTICLES.

FILED JULY1'3. 1922. I 2 SHEETS---SHEET 2 amvam m'ca which may be made in the desired form according to the process of the co-pending application No. 553,139, filed April 15, 1922. Material of this character has the advantage of being strong, while at the same time it lends itself to the uses herein described.

When electric light bulbs are packed they may first be pressed into the domes of the lower sheet and then have an upper sheet pressed thereon until each'butt makes a depression inthe dome aboveit, and is held as in a socket, or this operation may be reversed. This results in a packing such as that shown in Fig. 5, and provides for the packing of one or any desired number greater than one in a single box or other container. In each case the upper and lower packing unit sheets will be in contact with the container or otherwise held between the top and bottom thereof so that vertical movement cannot take place. The sheets should also be made so as to be co-extensive laterally with the container. In the modified form of Figs. 6 and 7 the projections are in the form of cone frustums 5 with a depressed interior portion 6 in the central aperture, and the edges of the chimney or other article are received in the annular recess 7 of the reverse side of the cone between it and the depressed middle portion, or received in the said depressed portion. This form may also be employed in the manner illustrated in Fig.

4, if desired.

. in described, if desired, but the units herein described when used in the manner set forth will render the use of other packing unnecessary in most instances.

What we claim is:

1. A packing unit for hollow fragile articles, comprising a fiat sheet having thereon dome-like rojections of concavo-convex form, forming prominences on one side of the sheet and concavities on the other, of a size to receive the ed es of the mouth of an article to be placed thereon and permit t to be ressed down into p'roximity with the flat s eet.

2. A packing unit for hollow fragile articles, comprising a fiat sheet having thereon dome-like projections of concavo-convex form, forming prominences on one side of the sheet and concavities on the other, of a size to receive the edges of the mouth of an article to be placed thereon and permit it to be pressed down into proximity with the flat sheet, said sheet being constructed and arranged to be placed in contact with said articles in normal or reversed position.

3. The pr0ce$ of packing hollow fragile articles having an open end with relatively sharp edges, which consists in providing a fiat sheet with concavo-convex portions approximating in size the diameter of an article at its open end, placing one of said sheets below and one above said articles wit-h the said concavo-convex portions opposite their. ends, and pressing the said articles against the said portions so as to engage the same.

4. The process of packing hollow l'ragilc articles, which consists in providing a flat sheet with concave-convex portions approximating in size the diameter of an article at end, placing one of said sheets below said articles with the said concave-convex portions opposite their ends, and pressing the said articles against the said portions so as to engage the same.

5. The process of packing hollow fragile articles. which consists in providing a fiat sheet with concavo-convex port-ions approximating in size the diameter of an article at its end, placing one of said sheets below said articles with the said cancavo-convex portions opposite their ends, and pressing the said article against the said portions so to engage the same, and forming depressions therein conforming to the said ends of the articles.

6. The process of packing hollow fragile articles having an open end with relatively sharp edges, which consists in providing a flat sheet with concavo-convex portions approximating in size the diameter of an article at its open end, placing one of said sheets below and one above said articles with the said c0ncavo-c0nVeX portions. opposite their ends, and pressing the said article against the said portions so as to engage the same and form therein a recess to receive and hold the said edges.

7. The process of packing hollow fragile articles, which consists in providing a. flat sheet with concavo-convex portions approximating in size the diameter of an article at its end, placing one of said sheets below said articles with the said concavo-convex portions opposite their ends, and pressing the said article against the said portions so as to engage the same and cause the said portion to enter the said article and frictionally engage its interior surfaces.

8. The process of packin hollow fragile articles having an open em with relatively sharp edges, which consists in providing a flat sheet with concavo-convex portions approximating in size the diameter of an article at its open end, placing one of said sheets below and one amve said articles with the said concavo-convex portions 0pposite their .ends, and pressing the said article against the said portions so as to engage the same, then placing other similar articles over the first-named articles with flat sheets having concavo-con'vex portions formed therein and plane connecting portions therebetween, said sheets heingnonof said portions.

ltll

structed and arranged to receive both open 15 ends of a hollow article of sheet material on the said concavo-convex portions, and said portions being formed so as to enter the said open ends and engage the inner surfaces of the article and also to receive one or both 20 of the ends of the article in the concave side Witness our hands this 23rd day of June, 1922, at the cit of New York, in the county and State of ew Yorlr.
